Transmission Cooling

The transmission fluid cooling system consists of:

• fluid cooler inlet and outlet tubes.
• an in-tank fluid cooler inlet tube.
• a non-repairable in-tank transmission fluid cooler.
• an auxiliary fluid cooler inlet tube.
• an auxiliary transmission fluid cooler.
• an auxiliary fluid cooler return tube.

The transmission fluid flows from the transmission to the in-tank transmission fluid cooler, to the auxiliary transmission fluid cooler and returns to the transmission.

For fluid cooler flow testing, backflushing and cleaning procedures, refer to AUTOMATIC TRANSAXLE/TRANSMISSION - 6HP26 article or AUTOMATIC TRANSMISSION - 6R75 article.
